Democratic Sen. Elizabeth Warren (Mass.) said President Donald Trump's 2016 election win in spite of losing the popular vote was the sign of an unhealthy democracy.

Speaking at the "2018 Ideas Conference" for the left-wing think tank Center for American Progress on Tuesday, Warren said the country's democracy was "crumbling around us." She cited Hillary Clinton's nearly three-million vote margin of victory in the popular vote over Trump as part of this "crisis."

"That is not exactly the sign of a healthy democracy," Warren said. "Democracy hangs on the idea that whoever gets the most votes wins. That's the central starting point, and it's worth repeating every single day."

At @CAP conference, Elizabeth Warren tells crowd that the fact that Trump won despite losing popular vote is a sign of an unhealthy democracy.

Clinton and other Democrats have called for the abolition of the Electoral College in the wake of her loss to Trump. She piled up huge wins in blue states like California and New York, but she failed to retain the "Blue Wall" of states like Pennsylvania, Michigan and Wisconsin, all of which Barack Obama carried twice.

Warren has been coy about her 2020 White House ambitions, insisting she's not running for president but not committing to serving out a full six-year term in the U.S. Senate if re-elected this November.
